Abstract
A detection method for a touch device includes transmitting a first uplink signal conforming to a first protocol of a first active stylus and transmitting a second uplink signal conforming to a second protocol of a second active stylus. A chronological sequence of the first uplink signal and the second uplink signal is based at least in part on whether the first active stylus or the second active stylus has just left a detection range of the touch device.
